<pre>llvm-objdump does not include the function name when disassembling with -l
(--line-numbers). I'm not sure whether or not this is desired/intentional.
$ cat foo.c
int foo() {
return 5;
}
$ clang -g -c foo.c -o foo.o
$ objdump -l -d foo.o
foo.o: file format elf64-x86-64
Disassembly of section .text:
0000000000000000 <foo>:
foo(): <--------- this line is missing below
/tmp/foo.c:1
0: 55 push %rbp
1: 48 89 e5 mov %rsp,%rbp
/tmp/foo.c:2
4: b8 05 00 00 00 mov $0x5,%eax
9: 5d pop %rbp
a: c3 retq
$ llvm-objdump -l -d foo.o
foo.o: file format ELF64-x86-64
Disassembly of section .text:
0000000000000000 foo:
; /tmp/foo.c:1
0: 55 pushq %rbp
1: 48 89 e5 movq %rsp, %rbp
